Chromosome structural variation of two cultivated tetraploid cottons and their ancestral diploid species based on a new high-density genetic map

Abstract A high-resolution genetic map is a useful tool for assaying genomic structural variation and clarifying the evolution of polyploid cotton. A total of 36956 SSRs, including 11289 released in previous studies and 25567 which were newly developed based on the genome sequences of G. arboreum an...
